The whistle should be blown at the end of the quarter. However the quarter doesn't end until a shot attempt ends. While the ball is in the air there shouldn't be a whistle. Blowing it at the sound of the horn is not correct. Rule 6.7.5 exception a.

Rule citation?

You need a rule to tell you when to blow a whistle?

No...just a justification, based on a written rule.

I agree that the FED has not established an official way to end a quarter. However, (Rule 1.14) "...... the audible timer's signal shall indicate that time has expired." I am not saying the whistle automatically ends the quarter or ends a try for goal if the shot is in the air. Putting a whistle to the audible signal/horn gives that official, as well as everyone in the gym, a reference as to where the ball is at that point. How would you ever get in trouble by putting a whistle to the scoreboard's horn at the end of a quarter?

In the OP, the T's whistle is a full second after the horn. Had he put a whistle on the horn, it may have helped him establish the fact that the ball was out of the shooter's hand at the time the horn sounded.

Agreed that if that shot was after the horn the whistle should have been blown a lot sooner. Also, it would be an ideal time to sell it (see other thread). The video didn't instill confidence that the shot was late. However, based upon the single clip I can't tell if it was after the horn or not.

Agree. Agree...video(s) inconclusive.

I'm not putting whistle on the play until it is dead. That means immediately if the ball is still in the shooter's hand when time expires. A legal shot in mid-flight is not getting a whistle from me. I will hit my whistle the shot goes through the basket or when it is obvious that the shot is no good.

Me, too.

And, fwiw, this specific procedure is in the NCAW CCA manual.

Agree 100%.

The Sounds Of Silence (Simon & Garfunkel, 1964) ...
 

Our local guys have been instructed not to sound the whistle to end a period, unless something "weird" happens to end the period (foul right before horn, shot not released before horn sounds, horn doesn't sound with all zeros, etc.)

I don't believe that there is anything in the NFHS Rulebook that states that an official shall sound his whistle at the end of a period. I don't believe that there's anything in the IAABO Mechanics Manual that that states that an official shall sound his whistle at the end of a period. I don't have access to a NFHS Mechanics Manual, but I would like to know what it states. A little help please ...

With the way they want us here to limit the number of unnecessary whistles, ie don't whistle subs in(unless timer is asleep), I don't see the need to whistle the end of the period either when its obvious that the whistle isnt needed.

100% correct as there could be a rebounding foul while the ball is still live during the try. If IUgrad has already blown his whistle, people are going to ask what his whistle was for and how does that impact the subsequent foul call.

Is this for real?

Do not get me wrong, there but for the grace of God go all of us into a pickle like this, but nothing about the second video is inconclusive.

Really nothing inconclusive about the first either (unless you are hearing-impaired) as the ball is already coming through the net when the horn sounds.

6A playoffs and they're still doing 2 man? That's a disgrace
